Title
(EN) COLORED INK FOR PAD TRANSFER PRINTING OF SILICONE HYDROGEL LENSES
(FR) ENCRE COLOREE POUR IMPRESSION PAR TRANSFERT SUR TAMPON DE LENTILLES A HYDROGEL SILICONE
Abstract
(EN)
The present invention provides a method for making colored silicone hydrogel contact lenses. The method of the invention comprises the steps of: (a) applying a color coat to at least a portion of at least one of molding surfaces of a lens mold with an ink, wherein the ink comprises at least one colorant, a binder polymer, an adhesion promoter, and optionally a diluent, wherein the binder polymer is a copolymerization product of a polymerizable mixture including (I) at least one hydrophilic vinylic monomer; (II) at least one functionalizing vinylic monomer containing at least one functional group selected from the group consisting of hydroxyl group -OH, amino group -NHR (wherein R is hydrogen or C1, to C8 alkyl), carboxylic group -COON, epoxy group, amide group -CONHR, and combinations thereof; (III) at least one silicone-containing vinylic monomer or macromer, and (IV) optionally one or more components selected from the group consisting of a polymerization initiator, a chain transfer agent, and a solvent, wherein the mold has a lens-forming cavity between the molding surfaces, wherein the colored coat contains a first surface exposed to the interior of the lens-forming cavity and a second surface in contact with the molding surface; (b) curing the ink printed on the mold; (c) dispensing a silicone hydrogel lens-forming material into the lens-forming cavity of the mold; (d) curing the lens-forming material within the lens-forming cavity to form the contact lens, whereby the colored coat detaches from the molding surface and becomes integral with the body of the contact lens.

La présente invention concerne un procédé de production de lentilles de contact colorées à hydrogel de silicone. Le procédé de l'invention comprend les étapes consistant: (a) à appliquer une couche de couleur sur au moins une partie d'au moins une des surfaces de moulage d'un moule de lentilles comportant une encre, l'encre contient au moins un colorant, un polymère liant, un promoteur d'adhésion et facultativement un diluant, le polymère liant est un produit de copolymérisation d'un mélange polymérisable renfermant (I) au moins un monomère vinylique hydrophile; (II) au moins un monomère vinylique de fonctionnalisation contenant au moins un groupe fonctionnel choisi dans le groupe renfermant un groupe hydroxyle -OH, un groupe amino -NHR (où R représente hydrogène ou alkyle C1 à C8), un groupe carboxylique -COOH, un groupe époxyde, un groupe amide CONHR et des combinaisons de ceux-ci; (III) au moins un monomère ou un macromère vinylique contenant du silicone, et (IV) facultativement un ou plusieurs constituants choisis dans le groupe renfermant un initiateur de polymérisation, un agent de transfert de chaînes ainsi qu'un solvant, le moule comprend une cavité de formation de lentilles entre les surfaces de moulage, la couche colorée contient une première surface exposée à l'intérieur de la cavité de formation de lentilles, ainsi qu'une seconde surface en contact avec la surface de moulage; (b) à durcir l'encre imprimée sur le moule; (c) à disperser une matière hydrogel de silicone formant la lentille à l'intérieur de la cavité de formation de lentille du moule; (d) à durcir la matière formant la lentille à l'intérieur de la cavité de formation de lentille pour former la lentille de contact, la couche colorée se détachant de la surface de moulage et devenant solidaire du corps de la lentille de contact.
